Do I have a virus causing this?
Any ideas?

Try plugging in an external mouse if you have one. If it runs smoothly, likely a touchpad issue.
If that also seems a bit spotty you may want to open task manager and see how the cpu load/memory usage is...is it high? Maybe something is hogging resources.
